Writes our submitter in Montreal: “I’m fortunate to live upstairs from my mom, who cleans my apartment when I’m busy with projects.” Recently, however, mom declared a litter-box boycott, as she explains in the note below.

I don’t typically like to post notes submitted by the person who left them, but I made an exception for this note by Geoff in New Zealand.

Writes Geoff: ”Someone actually threw out my lunch (still in its container) within an hour of putting it in the fridge at work. It was a really nice lunch., too. I thought someone had stolen it, then, for some reason I looked in the garbage can…it was covered in coffee grounds and snotty looking tissues. I was mad. Next day I brought lunch again. I wanted to be sure no one would even think of doing it again so I wrote the note, photographed it so my picture would accompany the note, and wrapped it around my lunch with elastic bands. No one has ever thrown my lunch out again.”

This year, one Boston neighborhood tried to ban the time-honored practice of using space-savers to reserve a parking spot after shoveling it. But old habits die hard…and somewhat violently.

When it comes to space-saving, says our submitter from Boston, “I get it. I respect it!” But after two of her own “space savers” were stolen, she figured the rules were off. One night, she says, “As I was looking for open parking , I pulled into an unclaimed space, thinking, what luck! No chair in sight!” Too good to be true, it turns out. When she returned to her car, she found this. (Thoughtfully kept dry in a plastic bag, I assume.)
